Alle folgenden sind also unterschiedliche Origins:

* `https://localhost`
* `http://localhost:8080`

Auch wenn sie alle in `localhost` sind, verwenden sie unterschiedliche Protokolle oder Ports, daher sind sie unterschiedliche „Origins“.

Aber schauen wir uns zunächst einmal diese grundlegenden **konzeptionellen Ideen** an. Diese Konzepte gelten auch für jede andere Art von Web-API. 💡

Im [vorherigen Kapitel über HTTPS](https.md) haben wir erfahren, wie HTTPS Verschlüsselung für Ihre API bereitstellt.

Die **FastAPI-Erweiterung** ist sowohl für [VS Code](https://code.visualstudio.com/) als auch für [Cursor](https://www.cursor.com/) verfügbar. Sie kann direkt über das Erweiterungen-Panel in jedem Editor installiert werden, indem Sie nach „FastAPI“ suchen und die von **FastAPI Labs** veröffentlichte Erweiterung auswählen. Die Erweiterung funktioniert auch in browserbasierten Editoren wie [vscode.dev](https://vscode.dev) und [github.dev](https://github.dev).
